Application filed December 1, 1915. Serial No. 64,545.

To all whom it may concern:

Be it known that I LEONIDAS BAXTER, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented a new and useful Improvement in Hydrocarbon-Lanterns, of which the following is a specification.

This invention relates to a new and useful improvement in hydrocarbon lanterns.

The principal object of the-invention is to provide for a hydrocarbon lantern of the type shown in my Patent No. 1,155,464, a device for preventing violent gusts of air being blown or otherwise forced into the air-inlet tube. When equipped with this device, which is simple and readily applied, the lantern may be placed in the wake of a strong draft or wind, or swung to and fro, without affecting the light. While it closes the air-inlet tube against violent gusts of air, the device is so constructed that, when applied to said tube, it will continuously admit a suflicient quantity of air for a successful operation of the lantern.

The preferred form of embodiment of my invention is illustrated in the accompanying drawings, of which Figure 1 is a side elevational view of a hydrocarbon lantern equipped with my improved wind-deflecting device; Fig. 2 is a side view of one end of the air-inlet tube, partly broken away, to show the position of the hook-shaped end of the device therein; Fig. 3 is a plan view of the disk-shaped end of said device; Fig. 4 is a plan view of the hook-shaped end thereof; and Fig. 5 is a plan view of the slotted disk itself.

Throughout the specification and drawings, similar reference characters denote corresponding parts.

In a detailed description of my invention the numeral 1 designates a reservoir base, 2 a tubular standard, 3 a frame and 4 an air-inlet tube of a hydrocarbon lantern which is exactly similar to the one illustrated and described in my above mentioned Patent No. 1,155,464. Accordingly, for a more detailed description of the said lantern, reference to that patent is recommended.

For the purpose of preventing violent gusts of air being blown or otherwise forced into the air-inlet tube 4, the following construction is provided for each end thereof. Preferably stamped from suitable metal is a,

relatively thin disk 5 containing a central elongated slot 6. Adapted to be passed through this slot and turned down upon the outer surface of the disk, are two lip portlons 7-7 of a slide 8 which is also preferably stamped from metal. These lip portions consist of two metallic tabs which pro ect, at a slight distance apart, from one edge of the slide. This ed e is slightly longer than the slot 6, where y, when said 11p portions are forced as far as possible through the slot and turned down, in opposite directions, upon the outer surface of the disk, the slide will be firmly secured to the disk at approximately right angles thereto. (See Figs. 3, 4 and 5).

The forward end of the slide 8 is of a width to permit its ready insertion in either end of the air-inlet tube 4. However, near its rear end the slide is enlarged to provide on each side thereof, a shoulder portion 9 adapted to engage the end of said tube when the slide is inserted therein.

Provided on the inner end of the slide 8, and of a width preferably less than that of the latter, is a spring hook-shaped portion 10 which is bent to bear rather tightly against the inner surface of the tube 4. The sides of the forward portion of said slide, while readily inserted, also have a relatively tight fit within said tube. Accordingly, when the slide 8 is inserted in the tube 4 as far as its shoulder portions 99 will permit, it will be firmly held therein. (See Figs. 1 and 2).

As will be observed from the figures of air-inlet tube 4. Furthermore, the shoulder portions 9-9 of the slides maintain the disks 5 at a sufficient distance from their respective ends of the tube 4, to permit air to freely enter the latter, but not in the vio lent gusts to which the tube would otherwise be exposed. The disks 5 break the force of these gusts sufliciently to enable the lantern to be placed in the wake of a strong draft or wind, or swung toand fro, without affecting the light.

Having described my invention, I claim:

1. In a hydrocarbon lantern, an air-inlet tube, a flat slide insertible therein, which leaves space on each side of it for the ingress of air, and a shield carried by the 91 6nd of said slide, beyond the tube, to

break the force of violent air currents directed toward the latter, substantially as described.

2. In a hydrocarbon lantern, an air-inlet tube, a flat slide insertible in said tube, having a relatively tight fit therein and leaving space on each side of it for the ingress of air, shoulders formed on said slide to engage the end of said tube,-whereby-to prevent its further insertion therein, and a shield carried bythe outer end of said slide beyond the shoulders of the latter, to break the force of violent air gusts directed toward the end of said tube, substantially as described.

3; In ahydrocarbon lantern, an air-inlet tube, an elongated metallic plate insertible inysaid tube, whose sides have a relatively tight-fit, therein, a spring member secured to the inner end of said plate for engaging the interior surface of said tube, to assist in firmlyholding the plate therein, a, shoulder portion-formed on each side of said plate nearits outer .end, whereby to prevent. its

further insertion in the tube, and aidisk of greater diameter :than the end of said tube,

secured to the rear end of said plate beyond its shoulder portions, to break the force of violent air gusts directed toward the end of said tube, substantially as described.

4. In ahydrocarbon lantern, an air-inlet tube, an elongated metallic plate having a rectangular portion insertible in said tube,
